Features and usage notes

Timer click

Here’s a description of individual pins from the DS1682 IC, taken from the official data sheet. Each of these is accessible through the mikroBUS pin

EVENT Input. The EVENT pin is the input the DS1682 monitors to

Timer click
determine when an event occurs. When IC/Module DS1682
the pin is pulled high, the contents of the

EEPROM are transferred to the ETC and the oscillator starts. The ETC begins to

Interface I2C, EVENT, ALARM
count in quarter-second increments.

Power 3.3V, 5V

Schematic also available in PDF

When the EVENT pin falls to logic 0, the supply
event counter increments, and the event counter, ETC, and user-memory data are stored in the EEPROM array. When the

Website

EVENT pin changes states, the 2-wire
bus is unavailable for communications for tEW falling and tER rising . The EVENT input is also deglitched tG to prevent short noise spikes from triggering
an event.

ALARM Active-Low Alarm Output. The DS1682 monitors the values in the ETC for the programmed value in the alarm register. When the ETC matches the alarm value, the alarm flag AF is set. Once set, the alarm flag cannot be reset. See the operating descriptions for the AOS and AP bits for details about the operation of the ALARM pin.

SCL 2-Wire Serial-Clock Input. The SCL pin is the serial-clock input for the 2-wire synchronous communications channel. The SCL pin is an input that requires an external pullup resistor.

SDA 2-Wire Input/Output. The SDA pin is the data input/output signal for the 2-wire synchronous communications channel. The SDA pin is an open-drain I/O, which requires an external pullup resistor.

N.C. No Connection. These pins are not connected internally.

Vcc +2.5V to +5.5V Input Supply

To switch between 3.3V and 5V power supplies, use the onboard jumper.
